Abstract

The utility model relates to a kind of tank drain filter devices, it included filter bottom leakage and filter mantle；The filter bottom leakage outer of crossing upwardly extends, and the filter mantle is opening down to be located at filter bottom leakage middle part；It the filter mantle and crosses in filter bottom leakage to be located on the outside of the filter mantle area of coverage and is distributed several first filter hole, described cross in filter bottom leakage is located at several second filter hole of distribution in the filter mantle area of coverage, the aperture of the aperture of first filter hole less than the second filter hole.A kind of the purpose of this utility model is to provide structures tank drain filter device simple, easy to use.Utility model has the advantages that filter mantle first once filters sewage, so that sundries was accumulated in filter bottom leakage peripheral side, avoid it from blocking the first filter hole, ensure that the smooth draining in pond.

Description

Tank drain filter device

Technical field

The utility model relates to a kind of tank drain filter devices.

Background technique

Existing tank drain filter device, mostly one layer single to cross filter bottom leakage, and draining parting is mainly by thereon Through-hole, however the through-hole aperture for crossing filter bottom leakage is too small, object is easy to block aperture, causes draining to have some setbacks, through-hole aperture is excessive, again The effect of parting is not achieved, is easy blocking sewer.

Summary of the invention

A kind of the purpose of this utility model is to provide structures tank drain filter device simple, easy to use.

The purpose of this utility model is achieved through the following technical solutions: a kind of tank drain filter device, it includes filtering Bottom leakage and filter mantle；The filter bottom leakage outer of crossing upwardly extends, and the filter mantle is opening down to be located at filter bottom leakage middle part； It the filter mantle and crosses in filter bottom leakage to be located on the outside of the filter mantle area of coverage and is distributed several first filter hole, it is described to cross in filter bottom leakage It is distributed several second filter hole in the filter mantle area of coverage, the hole of the aperture of first filter hole less than the second filter hole Diameter.

For the prior art, utility model has the advantages that filter mantle first once filters sewage, make miscellaneous Object was accumulated in filter bottom leakage peripheral side, avoids it from blocking the first filter hole, ensure that the smooth draining in pond.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of tank drain filter device embodiment of the utility model.

Fig. 2 is the top view of Fig. 1.

Label declaration: 1 crosses filter bottom leakage, 2 filter mantles, 3 first filter hole, 4 second filter hole, 5 lifting rods, 6 sealing covers.

Specific embodiment

The content of the present invention is described in detail with embodiment with reference to the accompanying drawings of the specification:

It is as shown in Figure 1 to Figure 2 a kind of embodiment schematic diagram of tank drain filter device provided by the utility model.

A kind of tank drain filter device, it included filter bottom leakage 1 and filter mantle 2；It is upward that the filter bottom excessively leaks 1 outer Extend, the filter mantle 2 is opening down to be located at 1 middle part of filter bottom leakage；It was located in the filter mantle 2 and excessively filter bottom leakage 1 It is distributed several first filter hole 3 on the outside of filter bowl 2 area of coverage, it is described to cross in filter bottom leakage 1 that be located at distribution in 2 area of coverage of filter mantle several Second filter hole 4, the aperture of the aperture of first filter hole 3 less than the second filter hole 4.

When draining, sewage first pass through filter mantle 2 and cross filter bottom leak 1 peripheral side, due to the first filter hole 3 aperture compared with Small, the sundries for only sewage being allowed to pass through, and carry secretly in sewage slides along filter mantle 2 and is crossing 1 peripheral side of filter bottom leakage, by first Sewage after filter hole 3 flows into downcomer by the second filter hole 4 again.Because sewage has already passed through primary filtering, by second The aperture of filter hole 4 is done larger, fast and easy draining.After having served as the sundries accumulation to a certain extent that filter bottom leaks 1 peripheral side, Discharge filtering device can be picked up, remove sundries.

It further includes lifting rod 5, and the lifting rod 5 leaked 1 bottom by extending downwardly out filter bottom on the upside of filter mantle 2, and 5 lower part of lifting rod is equipped with sealing cover 6.By pressing down on lifting rod 5, sealing cover 6 may make to block downcomer, and then realize envelope Mouth ponding effect.

Claims
